Seed presentation and availability for seed predators change during every plant reproductive cycle. We know very little about how those changes impinge on both the ability of seed predators to impact plant populations and the foraging costs associated with seed consumption. Therefore, we conducted several field experiments to evaluate whether wood mice Apodemus sylvaticus balance food and safet...

Synchronous populations of the chlorococcal alga Scenedesmus quadricauda were subjected to various irradiances, photoperiods, heterotrophic growth and chloramphenicol treatment in order to induce different cell cycle patterns. The courses of cellular and nuclear division, and of commitments to them, were followed to measure duration of growth and reproductive steps and to analyze their mutual i...

In this study, we examined the reproductive tracts of preserved specimens of the Great Basin rattlesnake (Crotalus lutosus) to investigate the reproductive strategies used by the only species of rattlesnakes widely occurring in a cold desert. The vitellogenic cycle of female rattlesnakes spanned over two consecutive years: females started vitellogenesis in late spring/early summer, and ovulated...
